This publication discusses best practices for managing and controlling weeds in container nurseries and greenhouses, focusing on woody plant propagation and containerized liner production.
Research has shown that up to 75% of the preemergence herbicides broadcast-applied to container nursery crops falls to the ground between the pots. As the size of the crop increases, the space between pots increases - -resulting in greater and greater percentages of the applied herbicide falling between pots. This factsheet covers how to apply preemergence herbicides to individual pots uniformly and accurately.
